Abstract

According to the present invention, a pin (10) is provided with a shoulder surface (11), a first seal surface (12), a first male threaded part (13), a second seal surface (14), and a second male threaded part (15), in this order from the tip end side of the pin (10). A box (20) is provided with a shoulder surface (21), a first seal surface (22), a first female threaded part (23), a second seal surface (24), and a second female threaded part (25). The first male threaded part (13) and the first female threaded part (23) have respective load flank surfaces (13d, 23d) each having a flank angle of less than 0°. The first male threaded part (13) is divided into an incompletely threaded section region (31b) and a completely threaded section region (31a), in this order from the side closer to the second seal surface (14). The incompletely threaded section region (31b) has a length of at least three times longer than the thread pitch, and has a thread height lower than the thread height of the completely threaded section region (31a). In the incompletely threaded section region (31b), gaps are formed between thread peak surfaces (13a, 23a) and thread root surfaces (23b, 13b).
